Given numbers are 322,561,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 322,561,217 is 5599902.
Find LCM of 322,561,217 with Prime Factorization
| 7 | 322, 561, 217 |
| 46, 561, 31 |
Multiply the prime numbers at the bottom and the left side.
7 x 46 x 561 x 31 = 5599902
Therefore, the lowest common multiple of 322,561,217 is 5599902.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
322 x 561 x 217 = 39199314
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
322 : 1, 2, 7, 14, 23, 46, 161, 322
561 : 1, 3, 11, 17, 33, 51, 187, 561
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,561,217, is 1.
Now, the common factors can be found like this.
322:2x 7x 23
561:3x 11x 17
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 39199314/(1x7)
LCM = 39199314/7
LCM = 5599902
Thus, we can understand that the LCM of 322,561,217 is 5599902.
